I have Anvil Studio installed on my Windows 10 partition my 2013 15” MacBook Pro, but I find it rather clunky to use. I also have MuseScore 3 installed on both the macOS partition on the same machine and on my 2009 Mac Pro tower, and I much prefer MuseScore. How nicely do MIDIs created & saved in MuseScore 3 play with the importer tool bundled with FEBuilderGBA?
I haven’t tried MuseScore
But I actually imported midis from Anvil Studio edited by myself and in FEBuilder they works great !! But yeah
Editing in anvil studio is a bit complicated. I spent hours just for edit a single midi
